Time-resolved spectroscopy at extreme pressure-temperature conditions The laboratory characterization of materials at extreme pressures and temperatures benefits greatly from in-situ spectroscopic measurements, including both optical and x-ray spectroscopy. Reaching and simultaneously probing the material at extreme conditions (e.g., exceeding 1 Mbar=100 GPa, and several thousand K) is challenging using either static and dynamic compression techniques. It requires experimental capabilities that overcome intrinsic limitations of studies at these conditions, such as high backgrounds, limited signals, short timescales, and the need for time-domain data and signal selection. Such spectroscopic methods can provide important information about the material state but also the P-T-strain rate conditions exposed. This session seeks contributions that use ultrafast spectroscopic approaches to enhance
understanding of matter under extreme pressure-temperature and also very high strain rate
conditions. In addition, it seeks to highlight technical demonstrations of new methods that probe
matter and provide metrology at such conditions. Alexander Goncharov: Carnegie Institution of Washington USA
